    Maybe overkill, but a feature-rich toothbrush

    This is a serious electric toothbrush. How that is to be interpreted can vary from one reader to another, but for me, I call it overkill. It may be perfect for some people. TLDR; on the last paragraph. I have used an electric toothbrush for a long time. I started with the a vary basic one a long time ago that had 2 speed settings. A few years ago, I bought a new one that had a few more features, but the thing I liked best about it was a setting for sensitive teeth, since it was a bit more gentle. I figured this Sonicare Prestige toothbrush, with it's 3 different settings, would be fine for my sensitive teeth since it had a lower speed setting. Fortunately, I was correct. However, this toothbrush has a LOT of bells and whistles when it comes to the settings. It has bluetooth capabilities, which allow you to connect to an app on your phone. This gives you 2 abilities: 1. Some of the settings on the toothbrush have to be changed through this app. 2. It guides you through brushing your teeth, helping you focus on one area at a time by highlighting an illustrated tooth chart and showing you what area to focus on. If you find that your visits to the dentist office don't go as well as you would like, meaning the hygienist finds areas that he/she suggests you spend more time brushing, this could be a great toothbrush for you. It is actually designed to "teach" you proper brushing techniques, while also adapting to how you brush. It encourages you not to brush too hard, but tries to help you get a really good clean. The combination of the brush itself and the app that accompanies it are a great tool that helps you learn better brushing techniques and to build a habit of maintaining those skills. For me, this brush is overkill. There are WAY too many features. The first couple of days trying to use it, I was so overwhelmed by all of the settings, and how to change them, along with all the different lights, colors, and meanings of those lights, that I actually found myself doing a poorer job of brushing. I felt like the electric toothbrush I had previously been using did a better job. Additionally, it took several more days to figure out what settings I wanted to use. What I found to be a big downside is the intensity "button". I put that in quotes because it's not physical button - it's more like a touch screen. That means that when I turned the brush in my hand to move to a different segment of my mouth, my thumb would accidentally touch this spot and change the settings. For a setting like this that you are unlikely to change once you start brushing, this really should be a physical button. The other setting that I don't care much for is a big change from most electric toothbrushes that I am familiar with. This brush divides your mouth into 6 segments, not 4. Instead of upper-right, upper-left, lower-right, and lower-left, you have the addition of upper-front and lower-front. I am not a fan of this feature and really wish there was a setting to change it back to 4 segments. When you have sensitive teeth, it is important to move the brush around, and repeatedly come back to each tooth, as opposed to just circling the same small area over and over, which this brush makes you do. I found myself essentially ignoring this and just moving around my mouth a bit more randomly, trying to guess where I was in the cycle. Two other items that I did not care for is the size of the outlet plus, along with a gap that exists right where the brush head meets the handle when fully assembled. I'll start with the plug. It's HUGE! It's a rectangular shape that sticks out from the wall so far that it could almost be an outlet shelf if it were just a bit wider. Since the battery is supposed to last 12 days (assuming twice a day for a single user), you could technically plug it in to fully charge it, and then put the charger away until you need it again. However, as rechargeable batteries degrade, eventually you will probably need to leave it plugged in more often. If you have a small crowded bathroom, or limited outlets in the bathroom, this is not good. I would rather have a "power brick" like you have with most laptop chargers that could sit on the counter. Finally, the gap between the brush head and handle is concerning to me. Philips acknowledges this gap and does not express concern, but being an oral hygiene tool that is exposed to moisture concerns me greatly when it comes to cleanliness. This gap is part of the design to allow for the vibration of the brush head, but I've never seen a design like this, and it seems like an area for harboring germs. I've taken to rinsing it very well, poring just a little mouthwash over it, and allowing it to air dry. TLDR; Even if you take generally good care of your teeth and feel that your brushing techniques are good, I guess this brush is designed to challenge that and could help you improve. Overall, it's a great tool for the right person, but I think the brush is a bit pricey even with these extra features. For me at least, it has a learning curve. Yes, for a toothbrush, it has a learning curve. I guess once you get used to it, this brush does a great job of caring for your teeth. If you are new to using an electric toothbrush, prepare to spend some time learning this device. If you are considering this brush as a replacement to a current electric toothbrush, you will likely gain at least one new feature considering all that this one has, but you may have to get used to some new ways of using an electric toothbrush.

    Toothbrush worked for 2 months and broke down. Got a replacement from Philips but it broke again. This time, Philips refused to fix it with no explanation and threatened with legal action if I attempt to misuse the warranty again!? Unbelievable. I purchased over 10 Sonicare toothbrushes in the last 12 years. Never getting Philips again. I showed the email from Philips at Best Buy and get a full refund right away.

    This version of the toothbrush has capacitive buttons, which are easily (and accidently) pressed changing the vibration pressure while you brush your teeth evertime. I highly dont recommend. Major design flaw
